To an whom it may concern:

" Be it known. that I, Gnnnnns E. Dam,

a citizen of the United States, residingin;

without the use of rivets, keys, or similar l t e ferring to thedrawings forming a part of this specification, Figure 1 is a plan viewpartly in horizontal section of a railway raft rigging embodying myinvention. Fi vie w of one of the halves of the draft yoke.

In drawings, 4, 4; are the draft or center sills or portions of the carframe to which the draft rigging is attached, 5 an end sill, 6 a bufierblock, 7, the draw bar carry iron, 8 the draw bar, 9 the draft yoke, 10the compression resisting member within the yoke, 11 and 12, the frontand rear followers respectively, 13, the tie plate, 14, 1 1 the stopmembers secured to the'center sills and provided with theshoulders, 15,15 forming stops for the front follower 11, and the shoulders 16, 16forming stops for the rear follower 12.

The draw bar 8 is provided with the usual shoulders 17, 17 which areengaged by the shoulders 18, 18 at the forward end of the yoke 9. Yoke 9consists. of two U members 19 and 19 in parallel arrangement side byside, each of said members consisting of an .upper strap 20 and lowerstrap 21 joined together at the rear end by the member 22 and at theforward end with the lateral flange 23, The shoulders 18 are formed bythe inturning of the forward ends of the straps 2O and 21." The flanges23 form between them and the forward portions of the straps 20 and 21 aboxlike opening within which the butt 24 of thedraw bar 8 is retainedwhen the gear is in normal position. The flanges 23 are fiaredinwardlyas'illustrated in Fig. 1 of the drawings so that on 2 is a sideelevation, and Flg. 3, a plan .,l,ater.al movement of the draw bar the potal p'oi nt inthednaw. bar s length "5 at the ;forward end of the yoke,as indicated by numeral 25 in Fig. 1. The members 19 and 19 are hingedtogether at their rear ends. each having a perforated flange 26, thesaid flanges being fastened together preferably by the bolt 27 providedwith the nut 28. In applying the yoke to the draw bar the yoke is openedand slipped over the butt of the draw bar from the sides, the followersand compression resisting member placed within the yoke, and all is thenput in position between the center sills and sustained therein by anysuitable means, preferably the tie plate 13. When in position betweenthe center sills, the shoulders 15, 15, between which the forwardportion of the yoke reciprocates, prevent the spreading of the twomembers 19 and 19 which thus see cures the draw bar within the hollowboxlike opening of the head of the yoke. On rearward movement of thedraw bar the same directly engages the follower 11 and on forwardmovement of the draw bar, the shoulders 17 of the same engage theshoulders 18 of the yoke.

I claim 1. A separable two-part yoke having a hooded forward endprovided with shoulders, a draw bar having co-acting shoulders engagingthe shoulders of the yoke, cheek platesat either side of the vokeadapted to engage said head and to hold the yoke against displacementfrom the draw bar.

4. In a device of the class described, draft sills, shoulders on saidsills, a yoke comprising two lJ-sheped members arranged side by side,said yoke having a hooded for- 10 Ward end provided with shoulders, adraw bar having oo-acting shoulders enghgin the shoulders of the yoke,the shoulders of the sills being adapted to engage the said head to holdthe yoke against displacement from the draw bar.
